Through various types of information-sensing equipment and technologies, information, such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., needs to be monitored, connected, and interacted with objects or processes. A huge network is referred to as the Internet of Things. It mainly aims to realize the connection between things and things and between people and things, so as to facilitate identification and management. Utilize the most advanced IoT technology at present to provide GPRS, SMS and other methods through GSM/GPRS/3G networks, through specialized industry terminals, to provide data collection, transmission, processing and service management for the majority of farmers. The "Standardized Production Monitoring System for Agricultural Greenhouses" is used to serve agriculture, rural areas and farmers, and to promote the development of modern agriculture in China by creating new values ​​for farmers' friends. In the modern greenhouse cultivation technology continues to develop at the same time, greenhouse stewards have been continuously promoted and applied, providing strong support for the development of equipment agriculture. Plus Wechat controls more relevant information:

The greenhouse steward system collects the key data of temperature, humidity, carbon dioxide content, soil temperature, soil moisture content, etc., which are the key to plant growth in the production process of agricultural greenhouses in real time through sensing equipment, and transmits the data to the operational support platform through the mobile network, and then gives The corresponding agricultural operation suggestions are proposed and sent to the corresponding user's mobile phone in the form of a short message; the remote diagnosis function can be realized. After the vegetable farmers shoot the vegetable pests and diseases through the system, the system is automatically transmitted to the management platform through the network and provided by the back-end experts. , issued prevention advice; at the same time with the existing shutter, micro-irrigation and other semi-automated equipment docking, through the mobile phone terminal to achieve greenhouse automatic roller blinds, greenhouse automatic sprinkler irrigation and other functions, to greatly increase the effectiveness of vegetable planting and monitoring and flexible Sex.
The vegetable farmers photographed the diseases through the camera provided by the greenhouse housekeeper and uploaded them to the system platform through the mobile network. The back-end experts can remotely diagnose the crops based on the photos of the disease symptoms and issue relevant prevention and control suggestions to the users to realize the pests and diseases. Expert remote diagnosis. She has extensive experience in the production, cultivation and pest control of greenhouse vegetables. Users can remotely control the switches of the roller shutters, exhaust fans and water valves in the greenhouse through the mobile phone or computer login system. The greenhouse housekeeper system can also control the inside and outside of the greenhouse according to the pre-set control logic. Actual conditions automatically open or close the shutter, exhaust fan, water valve and other greenhouse electrical and mechanical equipment. It can greatly reduce labor cost expenditure, increase productivity, and lay the foundation for intensive production.
